The K7 buggy was revealed this week and is designed to patrol grass, gravel, sand and other terrains, The Verge reported. Currently, the robot’s speed is limited to 3 mph.

Like the K5 security robot that patrols malls and parking lots, the K7 has sensors and cameras that monitor and relay video and audio back to a human. It navigates autonomously. The bots patrol, detect intruders and can scan license plates, but cannot detain people.

Knightscope Chairman and CEO William Santana Li told The Register that his company is “developing technology in the long run to be able to predict and prevent crime.”

"Crime has one trillion dollar negative economic impact on the United States every year,” he said. “It's a hidden tax we all pay in blood, tears, and treasure. And our long-term ambition is to literally be able to make the United States the safest country in the world, changing everything for everyone."

The bots are currently rented out to companies for $7 an hour, but the K7 price is not yet known.
